5.5 Electrical Characteristics

Over operating junction temperature range (T_J = –40°C to +150°C), V_IN = 3.0V or V_IN = V_OUT(nom) + 0.5V (whichever is greater), I_OUT = 1mA, V_EN = 2.0V, C_IN = 1.0μF, C_OUT = 4.7μF, and PG pin pulled up-to V_IN with 100kΩ, unless otherwise noted. Typical values are at T_J = 25°C.
